Those fidget spinners were tested for lead content by a Consumer Product Safety Commission-accredited laboratory, says U.S. PIRG. Toys tested for high levels of lead were re-tested to confirm results. Both test results were given to the CPSC, Target and Bulls i Toy.

The circle center of the brass Fidget Wild Premium Spinner tested for 33,000 parts per million (ppm) of lead. The circle center of the metal Fidget Wild Premium Spinner tested for 1,300 ppm of lead, the organization said. The federal legal limit is 100 parts per million (ppm) for lead in children’s products.

“Even small amounts of lead in toys can be ingested when transferred from fingers to mouth or from fingers to food," U.S. PIRG quotes a national lead expert Helen Binns, M.D., pediatrician at Ann & Robert H. Lurie Children’s Hospital of Chicago and Professor of Pediatrics at Northwestern University Feinberg School of Medicine, as having said. "Lead harms the developing brain and is easily ingested through normal hand to mouth behaviors."

The toy remains on Target shelves, as the companies defend their product with the Consumer Product Safety Commission's declaration that fidget spinners are not technically “children’s products” subject to legal limits for lead.

When the group contacted the CPSC, it says it received an email that called fidget spinners general use products that are only considered a toy if labeled for kids age 12 or under. The Fidget Wild Premium Spinners are labeled age 14 and over.

“Saying fidget spinners aren’t toys defies common sense, as millions of parents whose kids play with spinners can tell you,” said Kara Cook-Schultz, U.S. PIRG Education Fund toxics director. “The CPSC, Target and Bulls i Toy need to acknowledge the obvious — that all fidget spinners are toys."
